Hi.
I've build one this summer, maybe I'll be able to give you some help.
Do you have build the full 5 pots version?
I remember, when using this version, that a good clean compression could be hard to get. The pots interacts at lot.
Please let me know how you sets each pots.

Thanks everyone for the kind words.
The sticker is plain because the buyer just wanted it like that. I like to do simple and clean but I also like to put some graphics with it... another time... Maybe for the one I will build for myself ;-)

Is "bite" like the Ruetz mod on rats?  How effective is it? Do you notice anything when in "forbidden" mode?

Yes "bite" is the Ruetz mod. I find it very effective in the 3 "normal" gain mode. In "Forbiden/insane" mode it does strictly nothing.

What did you use for the opto? H11F1? I might be interested in that spare board by the way.

No, I've used H11F3. Banzaimusic have it. If you want a board, shoot me a PM. I've paid $29.85 for 3 boards, so 10$ + shipping for a board? For the rotary switch you'll need an AlphaSR1712F-0204. Mouser sells them.

Hello everyone!A guy asked me for a clone of a Bixonic Expandora, which I didn't know about, and I've discovered an interesting circuit.I designed a PCB and ordered it with OSH Park. I've choose to use a 2P4T rotary switch in place of the original internal DIP switches.
Everything turns great and you can see the results.
I've 1 PCB left over If someone is interested.
Thanks for reading!

Ahhh! Save me Jebus!

You should let the guy from Musikding know, I find him pretty responsive and helpful.

Yes, I insist. I think the Musikding team will be interested in the fact that some of their mn3101 are really 3102.
Mind the fact that he's in vacation right know.
I'm just saying: I have bought good mn3101 from musikding and banzaimusic.

Scruffie is the real guy about BDD circuit so I'll wait his input.
To the limit of my knowledge, I see that IC5 have only one input (pin 1 - Vdd) and it gives 2 important signals: CP1/2 & Vgg.
IC3 cannot works with a bad Vgg and yours his way too high. And it seems that IC5 have a good input Vdd so I guess the problem is with it.
It happen to simply have bad mn3101 even with a good source like banzai or musikding, it happened to me.
If you can't buy another one, and if you are in Europe, I can send you one for test purpose.

Hi there.
What I see is that IC5 doesn't produce the good Vgg. And as it get the right voltage on pin 1, I'll check every components attached to IC5: C29 first, R40/41/42, C30, Trimmer and Delay Pot. maybe D2 too?
I guess you don't have any other mn3101 for testing?

Do you have any demo links for the square wave generator?

I didn't record anything and I've already send it to the guy who asked for it.
But it was very much "inspired" by the Skychord's SleepDrone6.

I didn't find the schematic, so I've "conceived" something around the CD40106 as I've studied its use in the Weird Sound Generator...

I've been wondering about the Ginger circuit for a few months now. How do you like it

The Ginger was one of the first effect I designed a single sided board for, in 2014 I guess. It has never leaved my pedal board since! I love it: perfect gain, perfect crunch, good EQ.

Hi everyone!
Here's some builds I've done this last 6 months.
I've spent most of January & February playing with the littles synth thingy I've done in the end of 2017 and I've started building again in March.

1st, a Tenebrion reverb with some minor mods on the tone stack for a friend.
It's a single sided layout and it is one of my nicest one. Boards mounted pots. All the jumpers are under the brick.
If it's okay with Grind Custom FX, I'll share this layout some day.
Gut shot only 'cause I've forgot to take any of the box! It was plain, so nothing to see here.



Next is a Peach Fuzz work-alike.
I've design the PCB for 1590B for the guy wanted it in a 1590BB.
I've done something I've never thought of on this one: I've printed the top silkscreen on a cheap transparent sticker paper and put it on the board. I wish I had thought of that for my single sided Total Recall build!



I've make some mistake for the sticker so it's not perfect — you can see the drilling indication for the LED.


And the guts shot. I had to add a circuit for buffering and splitting the clean signal to make a Blend control.



At last, something I'm proud of.
It's a very simple 6 square waves generator based on the CD40106 chip. I took my time on designing this one and It turn great.
The top speak for itself.



The inside may look messy but it is in fact well organized. I could have shorten the wires a little bit.



I've a few board for this one left, If anyone is interested.

I almost forgot. I've redo the sticker for my Ginger build:



Thanks for reading!

After reading the thread at FST, I see an on/off/on SPDT...
Also, you can use a 1M pot for a full range selection.

Nice and clean builds!

Whaou!
Very impressive.
Gut shot, please!

At this point you really need an audio probe.
It's real easy to build and save sooooooo much time and headache!
You will then be able to trace the audio signal and found where it stop.
Also do you have the schematic (it helps to follow the signal) ?
